3 Claims. l This inventionrelates to newand useful'iniprovements in a telephone vcall counting device.

More specifically, the present invention proposes the construction of a'novel telephone counting device arranged to be placed adjacent a telephone in a manner to clearly indicate the duration of a billing period and the number of telephone calls completed at anytime during the billing period.

Still further, the invention proposes characterizing the counting device by a casing having a lfront wall with anupper horizontal shaft rotatively mounted withinthe casing and having a month indicator drum mounted thereon with an opening formed inthe front Wall of the casing through which a portion of the periphery of the month indicator drum lcan be seen With a retainer mounted on the outer face of the front wall below the opening in'a `manner to support a numbered card to be considered in conjunction with the visible portion of the month indicator drum to indicatethe starting and ending day of apar- `ticular billing period.

Another object of the -present invention proposes arranginga pairofshafts within the casing and upon the Yforemost of which three drums (units, tens and' hundreds) Aare individually rotatively mounted in amanner so that the numbers on their peripheries can be `successively viewed through `suitable openings formed in the front wall of the casing as the drums are rotated.

Still another object of the present invention proposes the provision of means on the rearmost of the pair of shafts for turning the tens drum in timed synchronization with the units drum in a manner so that the tens drum will be advanced one numeral each time the units drum makes a complete revolution.

The invention further proposes the provision of '1a means on the rearmost of the pair of shafts for turning the hundreds drum 4in timed synchronization with the tens drum in a manner so that the hundreds drum will be advanced one numeral `each time the tens drum'makes one complete revolution.

rA further object" of the present invention proposes forming each of the three drums along one of their sides with enlarged anges `which are extended through the front wall of thecasing to be usedformanually turning the drums back to zero.

AIt is a further object .of `thepresent invention to1providethe casingwitha manually operable means to bedepressed. once ,upon the completion of each telephonecall foradvancing the units 55 drum one numeral Vto-record the completedcall.

It is also an object of the present invention to slidably mount the units and hundreds drums on the foremost shaft in a manner to be slid slightly laterally away from the center tens drum in 'a manner so that each of the drums can be individually released to be turned-back to zero at the end of one billing period and the start of the next.

Another object of the present invention proposes the construction of a telephone call counting device which is effective for its intended purpose, which is simple and durable and which can be manufactured and sold at a reasonable cost.

For further comprehension of the invention, and of the objects and advantages thereof, reference will be had to the following description and accompanying drawings, and to the appended claims in which the various novel features of the invention are more particularly set forth.

In the accompanying drawings forming a material part of this disclosure:

Fig. 9 is a developed view of the numeral carrying portion only of one of the three drums.

Fig. 10 is a developed view of the month indicating drum per se.

The telephone call counting device, according to the present invention, includes a casing 2U having a top Wall 2|, a bottom wall 22, a front wall 23, side walls 24 and 25 and a removable back Wall 26. The casing 20 including the back wall is preferably formed of sheet metal but may, if desired, be Aformed of any one of the known resinous plastic Vmaterials .commonly used for such purposes-and the casing may be decorated or ,embellished in any desired fashion without l departing fromthe scope and intent of the present invention.

The rear of the casing 2U, except for theibaclc wall 25, is open and formed in its corners with four Small lugs 21. The corners of the back wall 25 are formed with holes and the lugs 21 are formed with aligned complementary threaded openings. Small screws 23 are passed through the holes in the back wall and are threaded into the openings of the lugs 21 for removably retaining the back wall 25 in position.

Rotatively supported in the vtop portion of the casing there is an upper horizontal shaft 29. One end of the shaft 29 is rotatively supported in a boss 30 formed on the inner face of the side wall 24. The other end of the shaft 29 is rotatively extended through the side wall and has xedly mounted on the outer end thereof a knob 3| by which the shaft 29 can be rotated. A collar 32 is fixed to the shaft 29 within the casing 29 and engages the inner face of the side Wall 25 to retain the shaft 29 against axial movement. f

Fixedly mounted on the shaft A*29 there is a month indicator drum 33 having the names of the month imprinted on the periphery thereof in aligned successive pairs as shown in Fig. 10. The 'front wall 23 of the casing 29 is formed with a pair of end aligned horizontal openings 34, see especially Fig. 1, through which one pair of 'aligned month names can be viewed.` One end lof the month indicator drum 33 has milled theregaged between adjacent teeth 35 for holding the .i

drum 33 in selected rotated positions in which vone pair of the aligned month names will be visible through the openings 34. The detent 38 is shaped to permit free rotation of the month name drum 33 in one direction or the other. Rotation of the month indicator drum 33 is accomplished through rotation of the shaft 29 by means of the knob 3 I.

Secured to the front face of the front wall 23 of the casing 29, there is a channel-shaped receptor 31 into which small cards 38 are to be selectively positioned. It is proposedl to include with the device of the present invention, a group ofthe cards 38 numbered chronologically'from 1,l to 31. The user of the device then selects Vthe proper number card 38 and slips it into position. in the receptor 31, as clearly shown in Fig. f'

'1, so that the number on the front of the card c anbe clearly read from the front of the device.

The number of the selected card then indicates Y the day of themonth on which the telephone billing period starts. For instance, from the .showing in Fig. 1 of the drawing, the billing period extends from the 16th day of March until the 16th day of April. l

` Included in the casing there s means for keepingtrack of the total number of telephone calls completed during any one telephone billing period. This means is comprised of a pair of shafts 39 and 40 extended parallel to each other and rotatively supported within the casing 29 below the shaft 29. The shafts 39 and 40 have their 'ends rotatively supported in bosses 4| on the inside faces of the side walls 24 and 25 of the casing 29. Positioned side by side on the fore- V most shaft 39 there is a units drum 42, a; tens 'drum 43 and a hundreds drum 44. The tens jdrum '43 is rotatively but nonslidablygretained Vthe hundreds drum 44 are rotatively and axially Y vslidably positioned on the foremost shaft'39 IOT units drum 42.

42 are each formed of separate parts xedly cona purpose which will become clear as this specication proceeds. Coaxially mounted on the ends of the foremost shaft 39 there are coil springs which operate between the adjacent faces of the bosses 4| and the units drum 42 and the hundreds drum 44, urging the drums 42 and 44 inward toward the tens drum 43 and more particularly against the collars 45 mounted on the shaft 39 on opposite sides of the tens drum 43.

The peripheries of the drums 42, 43 and 44 are provided with the numbers 41, see Fig. 9, in chronological order from 1 to 9 and zero and those numbers are arranged on the drums to be viewed through window openings 48 formed in the front wall 23 of the casing 29.

One side of the units drum 42 has milled in the periphery thereof ten teeth 49 and rotatively supported on the rearmost shaft 49 behind the units drum 42 there is a drive gear 59 having its teeth meshing with the teeth 49 or the units drum 42. The drive gear 59 is formed with a laterally extending hub 5| and a connector 52 has one end rotatively connected to the hub- 5| 'and its other end rotatively connected to the The hub 5| and the units drum nected together which permit the connector 52 to be rotatively engaged therewith. The connector 52 serves to connect the drive gear 50 to the units drum 42 so that when the drum is shifted longitudinally on the shaft 39, the gear will be moved longitudinally on the shaft 49 retaining the gear in constant mesh with the gear teeth 49 of the units drum.

The side of the drive gear 50 opposite the hub 5i and adjacent the tens drum 43 is formed with a laterally projecting cog 53. The side of the tens drum 43 adjacent the units drum 42, is formed with ten teeth 54. Each time the drive gear 50 completes one revolution, the cog 53 will engage between the adjacent teeth 54 of the tens drum 43 and turn the tens drum through one tenth of a revolution to advance it one digit. The relationship between the units drum42V and the tens drum 43 is such that the -tens drum will advance one digit each time the units drum is advanced from nine to zero.

The side of the tens drum 43, opposite the side thereof formed with the teeth `54, is formed with ten teeth 55. Rotatively but non-slidably mounted on the rearmost shaft 49 behind the -tens drum 43, there is a second drive gear 59 which has ten teeth meshing with the teeth 55 of Athe tens drum 43. The gear 55 is retained against sliding movements on the shaft 40 by means of collars 51 secured to the shaft 49- on opposite sides of the gear leaving it free for rotation relative to the shaft.

' The side of the drive gear 59 adjacent the hundreds drum 44 is formed with a cog 58. The side of the hundreds drum 44 isY formed with ten teeth 59 arranged to be acted upon by the cog 58. The synchronization between the tens drum 43 and the drive gear 56 is such that the cog 58 will engage the teeth 59 of the hundreds drum 44 and advance that drum one digit each time the tens vdrum 43 is advanced from nine to zero.

The casing 20 is provided with means, oper# able from the outside of the casing, which'is operative to advance the unitsv drum 42eme digit 'each time one telephone call is completed. The units drum advancing means comprisesY ard 59 slidably extended through` the top wall 2| vof the casing 20 and'through a bracketm `to the next digit.

Aaccesar mounted on the innerface of the top Wall 2|. The top-end of the rod '59, above the casing 29, is provided with a knob 6| by which the rod 59 can be conveniently depressed. 'Ihe rod 59 is of any desired cross-sectional shape so as not to rotate relative to the bracket 30 and the casing 29 and is retained in a raised position by a coil spring 62. The spring |52 is coaxially mounted on the rod 59 and operates between the top face of the bracketl 33 and a collar 63 mounted on the rod 59 so as to abut the inner face of the top wall 2|.

Pivotally mounted on the bottom end of the rod 59, within the casingV 20, there is a foot 64. The foot is pivotally attached to the bottom end of the rod 59 by means of a pin 65 and abuts the bottom end of the rod 59 so as to limit pivotal movement of the foot 64 with relation to the rod 59 to a rearward direction only or in a counter-clockwise direction as viewed in Fig. 3. The foot 34 is retained in an axially aligned position with relation tothe rod 59 by means of a leaf spring 56 secured to the inner face of the back wall 25 of the casing and which bears against the rear face of the foot 54.

The rod '59 and its operative foot 34 are positioned vertically within the casing 2) directly over one of the rearmost teeth of the drive gear 59 which drives the units drum 42. To advance the units drum 42 one digit, upon completion of a telephone call, it is merely necessary to completely depress the rod 59 until the knob 6I strikes the top wall 2| of the casing 20. During such downward movement the bottom end of the foot 54, will engage the tooth of the drive gear 53 llocated immediately therebeneath and advance the gear one tooth and similarly advance the units drum 42 and expose the next numeral thereof in the respective window opening 48. The pivotal mounting of the foot 64 permits it to pivot with relation to the bottom end of the rod 59 to follow the arcuate path taken by the tooth of the drive gear 50 upon which the foot i4 is operating. The rod 53 upon being released will be urged upward by the spring 32 and the bottom end of the foot 64 will snap back to its end aligned position with the rod 59 over the top of the next tooth of the drive gear 50, as shown in Fig. 3. The foot64 is returned to its end aligned position with relation to the rod 59. by means of the leaf spring 66.

Upon the tenth depression of the rod 59, the cog 53 of the drive gear 59 will engage the teeth or" the tens drum 43 and advance the tens drum pression of the rod 53, the units drum 42 will be advanced from nine to zero and the cog 53 will operate to also advance the Vtens drum 43 from nine to zero. As the tens drum 43 advances from nine to zero, the cog 58 of the drive gear 53 will function to advance the hundreds drum 44 to the next digit.

The drums 42, 43 and 44 are retained in rotative positions in which their numerals 4? will be properly aligned with the respective window openings 43 by means of flexible leaf springs El. The leaf springs Sl are secured at their bottom ends to the inner face of the front wall 23 of the casing and having their top ends formed with an untensioned bias to engage between adjacent teeth of the drums, as shown in Fig. 3. When the numerals of the drums 42, 43 and 44 are properly aligned with the respective window openings 43 of the front wall 23, then the springs 61 are under no load or tension.

Upon each one hundredth de- At the end of each-billing period, the total number of calls completed in that period can be quickly noted by viewing the numbers exposed in the window opening 48, as shown in Fig. 1. At the start of the new billing period, the drums 42, 43 and 44 must each be set back to zero manually. To accomplish the resetting of the drums back to zero, each of the drums 42, 43 and 44 is formed with an enlarged flange portion S3 which is extended through the front wall 23 oi the casing 20. More particularly, the flange portions 68 are extended through enlargements of the respective window openings 43, to be used to turn the drums 42, 43 and 44 back to Zero against the holding action of the respective leaf springs S1.

In turning the drums 42, 43 and 44 back to zero, the hundreds drum 44'is rst turned back to zero by rotating it by means of the flange portion 63 until the numeral zero of that drum 44 appears in the respective window opening 48. Next the tens drum 43 is turned back to Zero through the medium of its respective flange portion 653. However, before rotation of the tens drum 43 is started, the hundreds drum 44 is slid axially on the shaft SSagainst the action of its respective coil spring 46 and by means of its respective flange portion 68. With the hundreds drum 44 in the axially shifted position the tens drum 43 is turned back to zero and due to the interengagement of the drive gear 56 with the teeth the gea-r 53 will turn with the tens drum 43 to retain the proper synchronization of the numerals 4l of the tens drum 43 with the cog 53 of the drive gear 55. When the tens drum reaches its zero position, the hundreds drum 44 is released to be returned to its starting position yby the respective spring 43.

Finally, the units drum 42 is turned back to zero. This accomplished by rst moving the units drum 42 laterally away from the tens drum 43 against the action of the spring 4E. Due to the connection of the drive gear 50 with the units drum 42, through the medium of the connector 52, the drive gear 53 will also be moved laterally on the rearmost shaft 4i). Movement of the drive gear 53 moves that gear away from the bottom end of the foot 34 and moves the cog 53 away from the teeth 54 of the tens drum 43 leaving the units drum 42 and the gear 50 free to rotate, while being held in the laterally shifted position, to align the numeral zero of the units drum 42 with the respective window opening 48. When that position is reached, the iiange portion S3 of the units drum 42 is released and the respective coil spring will return the drum 42 and the drive gear 50 to their starting positions in which the drum 42 bears against the adjacent collar 45. When the drums 42 and 44 are shifted laterally on the shaft 33, the teeth of those drums engaged by the leaf springs 6T will move away from the leaf springs; however, the vleaf springs will retain their normal positions due to their untensioned bias when engaged between the teeth of the drums to reengage the teeth of the drums when the drums are released and urged back to their starting positions by the respective coil springs 45.

Mounted upon the side wall 24 of the casing 20, there is a small transparent container 69 divided into spaced bulbous portions by a reduced neck portion having a small passage connecting the interiors of the bulbous portions. The interior of the container 59 has a quantity of sand 19 which will require three minutes to pass from one bulbous portion of the container 69 to the other through the reduced neck portion. The container 69 is mounted on a bracket H which is rotatively mounted on the side wall 24 of the casing 20. By turning the container B9 with relation to the side wall 24 to position the bulbous portion thereof having the sand 'l0 at the top so that the sand will pass through the passage of the reduced neck portion, the container 10 can be used to time one telephone call so as to limit it to three minutes or any multiple of three minutes by repeatedly turning the container 69 through one hundred and eighty degrees.

While I have illustrated and described the preferred embodiment of my invention, it is to be understood that I do not limit myself to the precise construction h'erein disclosed and the right is reserved to all changes and modifications coming within the scope of the invention as defined in the appended claims.
